Interset and set-to-total correlations for the California Card Sorting Test were studied for 135 college students and 63 elementary school students. Although subsets were not equivalent, the generally good correlations between subset and total test scores indicated that use of the individual subsets as short forms is justified. (SLD)

Describes two new exercises in classical conditioning that use earthworms and houseflies. The animals are available year-round and pose no risk to the students or instructor. The conditioned stimuli are odorants. These elicit a conditioned response of contraction in worms or proboscis extension in flies. (MJP)

Investigates the effects of two instructional strategies, visual display (animation, and static graphics with and without motion cues) and contextual presentation, in the acquisition of electronic troubleshooting skills using computer-based instruction. Study concludes that use of visual displays and contextual presentation be based on the…

The experience tutoring a student who is blind in four semesters of university calculus is discussed. The mechanics, instructional strategies employed, and the challenges encountered are examined as they relate to teaching mathematics. It was found there are important similarities and also differences as compared to sighted students in teaching…

A multiple baseline design across three parent-child dyads of families with multiple risk factors was used to determine the effectiveness of teaching parents to use milieu language teaching procedures. Parents were taught to use two sets of milieu language teaching skills: responsive interaction and incidental teaching. Results showed that parents…

The present study employs event related potentials (ERPs) to verify the utility of using electrophysiological measures to study developmental questions within the field of language comprehension. Established ERP components (N400 and P600) that reflect semantic and syntactic processing were examined. Fifteen adults and 14 children (ages 8-13)…

The attentional blink refers to the finding that the 2nd of 2 targets embedded in a stream of rapidly presented distractors is often missed. Whereas most theories of the attentional blink focus on limited-capacity processes that occur after target selection, the present work investigates the selection process itself. Identifying a target letter…

Research on perception and cognition suggests that whereas East Asians view the world holistically, attending to the entire field and relations among objects, Westerners view the world analytically, focusing on the attributes of salient objects. These propositions were examined in the change-blindness paradigm. Research in that paradigm finds…

Overselective stimulus control was assessed in 29 students at residential schools for individuals with developmental disabilities. Overselectivity testing included three different delayed identity matching-to-sample tasks. Sample stimuli for the Form/Color Test were nine possible combinations of three colors and three forms. On each trial, the S+…

Today's "out-of-school learning" is dominated by PC games, videos, and TV. These media provide children with optimal conditions for nurturing their visuospatial intelligence. In "chemistry" and biochemistry, over the past 125 years, thinking has shifted from the "logical-mathematical" to the "logical-visuospatial." In chemistry visuospatial…

Of all the sciences, biology has probably made the most rapid progress in recent years and the need for this to be reflected in a new Advanced Level biology course has long been recognised in the UK. After wide-ranging consultation and successful piloting in over 50 schools and colleges in England and Wales, the new Salters-Nuffield Advanced…

Background: The underlying behavioral/psychological processes of attention-deficit/hyperactivity disorder are unclear. Motivational factors, related to dopamine dysfunction, may play an important role in the development of the behavioral symptoms. Particularly, infrequent, but not frequent, reinforcers have been suggested to be associated with…

Background: Unusual responses to sensory stimuli are seen in many children with autism. Their presence was highlighted both in early accounts of autism and in more recent first-person descriptions. There is a widespread belief that sensory symptoms characterize autism and differentiate it from other disorders. This paper examines the empirical…

Background: Debates about the developmental origins of adult face processing could be directly addressed if a clear infant neural marker could be identified. Previous research with infants remains open to criticism regarding the control stimuli employed. Methods: We recorded ERPs from adults and 3-month-old infants while they watched faces and…

Intergroup attitudes were assessed in African-American (N=70) and non-African-American minority (N=80) children, evenly divided by gender, in first (M=6.5 years old) and fourth (M=9.6 years old) grades attending mixed-ethnicity public schools in a suburban area of a large mid-Atlantic city in the USA. Children were interviewed to test hypotheses…
